This is the G311027525 model from Qioptiq Photonics, a 22.4 mm diameter UVFS Double-Convex Lens designed for use in the 725-1050nm wavelength range. The lens boasts an effective focal length (EFL) of 80mm, making it suitable for a variety of optical applications.
The lens is spherical in shape, with a base shape of a circle. The geometry of the lens is defined by its edge thickness of 1.7mm and center thickness of 3.3mm. The first radius of curvature (R1) is 78.298, while the second radius of curvature (R2) is -78.298, indicating a symmetric convex-convex design. The inner and outer radii are both 0, suggesting a uniform curvature throughout the lens.
The lens is made from UVFS material, specifically identified as UVFS Mal-1965. This material is known for its excellent optical properties, making it ideal for use in high-precision optical systems. The lens is unmounted, allowing for flexibility in its integration into various optical setups.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
